Beit known that I, HIRAM A. BOND, a citizen of the United States of America, and a resident of Springfield,in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Shuttles for Tire-Looms, of which thefollowing is a full, clear, and exact description.

This invention relates to conjoint improvements in the shuttle and shuttle-carriage of a loom, which general description of shuttle and carriage is found in the well-known Lyall loom, wherein the shuttle-carriage connected to a flexible band or belt runs along on a trackway therefor on the lay-beam under the shed and the shuttle having rolls is supported and has its movements imparted thereto by the carriage, its location being Within the shed, the shed changes or warp-wire crossings taking place after each traverse of the shuttle and its carriage and when the same are at either end of the lay-beam and outside of the warps.

The obj ect of the present invention is to improve the shuttle and shuttle-carriage in respect of small but important features, whereby they become practicable and satisfactory for utilization in a loom of the class described in Letters Patent of the United States issued to me October 15, 1901, No. 684,536, and March 8, 1904, No. 754,192, and which loom is particularly designed for the weaving of a high grade of wire-cloth, such as is used in Fourdrinier paper-machines. In the weaving of such wire-cloth the wire employed is very iine, soft, or ductile, and delicate, easily stretched, kinked, or distorted, and it is therefore requisite that the combined shuttle and shuttle-carrier shall be so constructed for cooperation one with the other as to avoid injury to the warp-wires.

Under the provisions of the invention the shuttle will be kept truly and properly in its course across the loom and between the upper and lower divisions of the Warps and without tendency to acquiring any improper change of direction.

Incidental to constructions it becomes practicable to operate the loom making an unusually low shed, so that the Warp-wires will not become strained or stretched.

The invention consists incertain particular and peculiar features of constructions, forms of parts, and combinations of parts in the shuttle-carriage and the shuttle made with reference to its coperation therewith,

all substantially as hereinafter described, and set forth in the claims.

In the drawings, Figu-re 1 is a side view of the shuttle and the shuttle-carriage represented as between a supporting runner-way and a bearing-bar, both appurtenant to the lay of the loom. Fig. 2 is a cross-section as taken on the line 2 2, Fig. 1. Fig. 3 is a perspective view oi the shuttle-carriage and portions of the band connected to the opposite ends thereof. Fig. 4 is a plan view of the under side of the shuttle with the middle portion thereof broken away and in section showing the bobbin and bobbin-holder therein. Fig. 5 is a plan view of the top of the shuttle. Fig. 6 is a sectional view through the bobbinholder and bobbin as taken on an intermediate plane thereof at right angles to the axis of the bobbin. Fig. 7 is a perspective view of one of the metallic j ournal-constituting f1ttings for the shuttle.

' Similar characters of reference indicate corresponding parts in all of the views,

In the drawings, A represents a portion of the laybeam of the loom, the same being equipped with the trough-shaped runner-way B for the shuttle-carriage C and having thereab ove, forward of the reed a and carried at the under side of the reed-cap, the bearing-bar D, it being understood with, reference to Fig. 2 that the battening is in the direction toward the letter 11, 1/ y representing the warp-wires making the shed, and F represents the shuttle supported by the carriage and so engaged therewith as to be drawn backwardly and for wardly thereby, the location of the shuttle being within the shed and having to roll over the lower set of warp-wires in its movements with the carriage, to which the back-and-forth movements may be imparted by novel means Such as set forth and claimed in Letters Patent No. 785,655.

The carriage Cfendwise connected with the band or belt 10, is made in the form of an approximately rectangular frame having Within the aperture thereof the lower pair of rollers 12 12, extending slightly below the under surface of the carrier-frame to roll on the runner-way B, and the upper pair of rollers 14 14 in peripheral contact on the rollers 12 and acting as idlers for communicating rolling motions in the right directions to the pair of lower rollers 15 of the shuttle, these rollers being axially slightly nearer together than the pair of rollers 14 14 of the carriage, so as to be more or less nested and engaged there- IOO IIO

the tendency which the shuttle might more naturally have to settle laterally toward the l beating-up point and become bound in the The shuttle has the rectangular cavity c convergent space between the rollers 14 14 therein for the bobbin-holder 7i and bobbin l), of the carriage and the under surface of the Carried therein with the delivery-mouth d, in i lay bearing-bar l). A further peculiarity in which are the grooved wire-guide rollers c c. the action of the carriage and shuttle moving The under side of the bearing-bar D is inl conjointly therewith is that the rolls 14 14 clined downwardly and forwardly toward l and 15 15 traverse all of the lower series of the beating-up point on an angle about corwarp-wires in each crossing movement of the responding to the inclination of the upper shuttle, and inasmuch as the carriage has Wires of the shed, and the upper side of the considerable freedom or side lash in its runshuttle is correspondingly inclined, although ner-support B there is a constant vibration the height of the shuttle is not such as to brin and slight changing between the adjacent its top to contact with the under surface of pairs of rollers 14 and 15, especially in that the bearing-bar, the rollers ff, mounted withthey are not always strictly axially parallel, in the upper part of the shuttle-body and near but there is a scissors-like working at their the ends thereof, having rolling contact peripherally adjacent surfaces, the tendency against the inclined bearing-bar D. Each of which near their central parts is to nip and of these rollers regarded. as a whole has its kink or distort more or less of the warp-wires, periphery beveled from end to end on an inacross and at opposite sides of which the rolls clination corresponding to that of the under move, and in order that such result may be surface of the bearing-bar; but these rollers obviated one of each of the adjoining rollers are made in opposite end halves or sections 14 15 has a central recess or rabbet, as repre- 16 16 to overcome liability which they might sented at 30, the recessed rollers in the illushave in their rolling contact on the bar to ditrations here given being the idler-rollers 14 Vert the shuttle from its desired straigl'it of the carriage, although the under rollers 15 course, owing to the inequality in the diameof the shuttle might be the ones intermediters at different portions of the rollers. ately rabbeted for acquiring the same eect.

The shuttle-body has at its end portions The bobbin l), as seen in Fig. 2, is in the the apertures 17, at the opposite parallel ends form of a flat spool having the end flanges or of which are the inset journal-bearing blocks heads, and the same is set within and carried 18, the same having the alined j ournal-holes for its rotation by the bobbin-holder iv,which 19 and the perforated oppositely-offset ears is in the form of a sheet-metal U-shaped 20, through which the screws 21 are passed strap having dimensions to be crowded into to secure the blocks in the mortises therefor the slmttle-aperture c and frictionally held in the wooden shuttle-body. therein by the elasticity of the side members rllhe round journal rods or shafts 22 are exof th-e holder, and the wire may run in the tended into the holes 19 of the blocks or iitcourses represented by the full line and dottings 18, and the beveled roller-sections 16 ted line, Fig.4,and, as guided by the grooved 16 turn on the shafts 22 independently of rollers e @,aecordingly as to`whether the shuteach other, and in actual practice in the tle is moving to the right or to the left across mounting of these divided beveled roller-secthe loom in the shed. Located within the tions 16 16 on the shuttle-body they are arbobbin-holder is a shoe s, pivotally connectranged axially very slightly inclined from ed to and between the sides of the holder, as lines truly perpendicular to the longitudinal indicated at m, said shoe being arranged to line of the bobbin. rlhe degree of this anguswing against the convolutions of the wire larity is so slight as to be imperceptible and wound on the core or central body of the not capable of observation in a drawing: but the inclinations of the axes are on trends indicated with great exaggeration by the lines 9 on Fig. 5 convergent toward the thicker or high side of the shuttle-body, and the axial inclination of one of the sectional beveled rollers may be slightly greater than that of the other to compensate for the difference of the draft or tension of the wire when drawn off toward different ends ofthe shuttle, as occurs on the reverse motions of the latter.

By arranging the sectional rolls slightly axially inclined to the true transverse line of the shuttle-body the shu-ttle has a tendency to crawl upwardly on the inclined surface of the bearing-bar toward the reed working, as it were, up on a side hill and nullifying within, as represented in Fig, 1, for the usual j communication of motion bodily to the shutj tle by the carriage. j

by the spring t, one end of which is fastened, as indicated at t2, to the back or uniting member of the holder. The spring is under the greatest compression when the bobbin is full, such compression and tension lessening, as it is desired thatit should, as the wire is used off therefrom. The bobbin is heaviest and will acquire more momentum for rotation when 'full than when the supply is diminished, and consequently the spring-pressure counteracts the difference in momentum, giving practical equality of wire-delivery.

With reference to Fig. 4 it will be seen that when the wire runs off at the angle of the full line e its withdrawal is under some- IOO IIO

bobbin and to be held with yielding pressure what more tension than when the strain is on the different tangent line represented by the dotted line v2, which shows the course of the Wire when the shuttle is moving in the other direction, the variations having tendencies to variably change the degree of divergencies of the shuttle laterally from its required course across the loom and through the shed, and these variable tendencies to such deflections are provided against or rectified by the slight angularity in the setting of the aXes of the beveled sectional rollers 16 16, the inclination of the axis-line of the left-hand sectional roller being somewhat greater than the inclination for the right-hand roller, but the inclinations of both being so slight as to be imperceptible, and the indication thereof is only relied on in the drawings by 9 9, Fig. 5.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with the lay-beam having a runner-way and ashuttle-carriage movable therein, having peripherally-contacting pairs of rolls axially transverse of the length of the carriage, said beam having a bar above the runner-way with its under surface inclining downwardly from its rear to its front edge, of the shuttle having a body provided with rolls at its under side arranged to ooact with and adj oin Within the upper pair rolls of the carriage, and having at its upper side rolls in paired, axially-alined, separate, independently e rotatable sections having their peripheries beveled to correspond with the inclination of the aforesaid bar of the laybeam.

3. The combination with the shuttle-car-- riage having rolls in pairs axially transverse of the length of the carriage and in peripheral contact, and a runner-way on the lay for the carriage and a bearing-bar on the lay above the runnereway, having its under surface inclined downwardly from its rear to 1ts forward edge, of the shuttle having in the un der part of the body thereof a pair of rolls axially parallel on lines transverse of said body,

and arranged for disposition within and adjoining the upper rolls ofthe carriage, one set of said adjoining rolls being centrally peripherally rabbeted, and rolls at the upper portion of the shuttlesbody composed of aXiallyalined, separate, independently-rotatable sections having their peripheries beveled t0 correspond with the inclination of the said bearing-bar of the lay.
